So I have a new build that I've been playing games on, but when I am playing the games, I get huge lag spikes which makes it completely unplayable. On BF4 I get 40-70 on pings, but it shoots up to 800+ randomly and then goes back down, then goes up again. It's very frustrating and makes any game unplayable. I've been using the wifi that comes with the Asus rampage IV black edition, I have full signal for the wifi so I know that's not the issue.
My build : Asus rampage IV black edition
GTX 780ti kingpin edition
32gb gskill ram
Samsung 840 pro
